Wind chill readings are expected to drop to as low as 24 degrees below zero with winds during the day up to 20 mph and, on Friday, up to 25 mph, the weather service website said.

"Hypothermia can occur rapidly in those unprepared for the cold. Any exposed skin can experience frostbite within a few minutes," the weather service said.

While the advisory covers all of Ohio, in Stark County the temperature was expected to reach a high of 12 degrees Thursday before dropping to zero overnight into Friday. The forecast included subzero wind chills, meaning that it could feel more like 10 degrees below zero during the day Thursday, 16 below on Thursday night and minus 17 on Friday.

At 12:30 p.m. Thursday, conditions at the Akron-Canton Airport were listed as "light snow" with a temperature of 10 degrees and winds out of the northwest at 17 mph and a resulting wind chill reading of 8 degrees below zero.
